+## VRAHerbicide API
+[<< Home](https://git.akkerweb.nl/FarmMaps/Documentatie/wiki/Home)  
+
+FarmMaps is an asynchronous architecture, the API flow keeps this in mind.
+The API expects that all data is already processed and available provided, for example through the normal FarmMaps flow (frontend).
+
+For the currently available public FarmMaps API you can take a look at swagger: http://farmmaps.awtest.nl/swagger/index.html  
+
+**Input preperation**
+* Users can upload their own data if needed. (in case of when FarmMaps has not processed the required data).
+    * The farmmaps file API can be used for this.
+
+**Users can poll the task api to see if a task is completed**  
+**This can be achieved with the task execution id obtained from calling the 'ItemTask' API.**  
+[Poll task status](https://git.akkerweb.nl/FarmMaps/Documentatie/wiki/Polling-task-status)  
+
+**Users can query the API for child items of a cropfield to see what items it has.**
+
+### API flow
+* Authenticate User
+* Optional steps
+    * *Create cropfield through FarmMaps API*
+        * Item 'vnd.farmmaps.itemtype.cropfield' must be created with its data as specified in the api.
+        * Task 'vnd.farmmaps.task.workflow' needs to be executed to aggregate all needed data.
+            * This is an asynchronous process and can take a while before all data is collected in FarmMaps.
+    * *Upload own data*
+        * IF shape data, convert to geotiff.
+* Task 'vnd.farmmaps.task.vraherbicide' must be executed to create an application map.
+* Task 'vnd.farmmaps.task.taskmap' can be executed to create a taskmap.
+* Download item data (tiff of shape)

+### Steps
+[Authentication](https://git.akkerweb.nl/FarmMaps/Documentatie/wiki/Authentication)  
+
+##### Optional
+[Create Cropfield](https://git.akkerweb.nl/FarmMaps/Documentatie/wiki/Create-Cropfield)  
+[Upload Data](https://git.akkerweb.nl/FarmMaps/Documentatie/wiki/Upload-Data)  
+
+###### Transform shape to geotiff
+The VRAHerbicide task only processes tiff items as input.  
+If your input data is a processed shape file it first needs to be converted to geotiff, this can be done with the 'ShapeToGeoTiffTask'.  
+
+Pass the code of the shape item into the {code} parameter, this creates a new item with tiff data as the parent of the shape item.  
+This new geotiff item should be used as input to the a task.

+> Request
+```javascript
+POST /api/v1/items/{code}/tasks
+{
+  "taskType": "vnd.farmmaps.task.shapetogeotiff"
+}
+```  
+> Response 201
+```javascript
+{
+  "code": "string",
+  "taskType": "vnd.farmmaps.task.shapetogeotiff"
+}
+```
+
+Response 400 Tasktype not found  
+Response 401 Not authenticated  
+Response 403 No WRITE permissions in item  
+Response 404 Item not found  
+
+###### Querying predefined herbicide agents.
+A list of herbicide agents can be requested by finding the "vnd.farmmaps.package.vra.herbicide" items, taking the first item found and reading it's data field 'agents' array content.  
+> Request
+```javascript
+GET /api/v1/items/?it=vnd.farmmaps.package.vra.herbicide
+```
+> Response 201
+```javascript
+{
+    "code": "....",
+    "data": {
+       "agents": [
+           {

+    }
+}
+```

+Response 401 Not authenticated  
+Response 403 No READ permissions in item  
+Response 404 Items not found  
+
+###### Creating an application map with the VRAHerbicide task
+Execute the task with the item code of the cropfield as parameter inside {code}.  
+Use the input map code inside {itemCode}, specifying an inputCode for the input data item.  
+
+{itemCode} needs the code of the data input item passed into it.  
+An **optional** {extraItemCode} can be passed inside the 'extraInputcode' field to process herbicide from 2 inputs.  
+Fill in the agent field with an agent gotten from the herbicide agents query discussed above.  
+
+The resulting application map will be created as a child item of the cropfield item (this can be queried).
